C++ program to calculate sum of all natural numbers using recursion
#include<iostream>
using namespace std;
int getSum(int N);
int main() {
int n;
cout << "Enter an Integer\n";
cin >> n;
cout << "Sum of Numbers from 1 to " << n << " = " << getSum(n);
return 0;
}
int getSum(int N) {
if(N >= 1)
return N + getSum(N-1);
else
return 0;
}
Output
Enter an Integer 10 Sum of Numbers from 1 to 10 = 55
